Never seen the commercial. I can recite 'shamwow' and 'enzyte' ads word for word, as I work nights too. I have two black cars so it got my interest until i saw the text below on your link:
*As a bonus, you can get the Auto Lens Renewer Kit for FREE, just pay separate $19.99 S&H
I was about to say most lens kits out there work nice and make the package worth the money. whats this? Ebay style shipping price! Nevermind!
